Specication of Letters Patent.

Application led October 11, 1909. Serial No. 522,151.

Patented Apr. 19, 1910.

To all whom'fit may concern:

Beit known that I, WILLIAM C. Blusen, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Link Belts, of which the following is a specication.

The object of my invention is to provide a link-belt composed of a series of duplicate arts of such form as to be readily manuactured, assembled and separated.

The accompanying drawmgs illustrate my invention.

Figure 1 is a plan in partial horizontal section of a portion of chain constructed in accordance with my invention, the side bars being formed integrally with .the cross bar and provided with locking lugs and flanges;

Fig. 2 is a similar view of a modified form, in which the locking flanges and lugs are omitted; Fig. 3 a section on line 3 3 of Fig. 1; Fig. 4 a section on line 4 4 of Fig. 1; Fig. 5 a section on line 5 5 of Fig. 2; Fig. 6 a section on line 6 6 of Fig. 2; Fig. 7 aview similar to Fig. 1 but in which the side bars are separate from the cross bar thus providin for a roller construction; Fig. 8 aview slmilar to Fig. 7 but showing a modification in which the lockin lugs and flanges are omitted; Fig. 9 a sectlon on line 9 9 of Fig. 7; Fig. 10 a section on line 10-10 of Fig. 7; Fig. 11 a section on line 11 11 of Fig. 8; Fig. 12 a section on line 12-12 of Fig. 8.

In Figs. 1 and 2 of the drawings, 21, 21 indicate a pair of side bars of a link which side bars are disconnected at one end but at the opposite end are connected by cross bar 22. The free end of each side bar 21 is pro-v vided with an inwardly projecting lug 24 which is iared toward its free end, as clearly shown in Fig. 4 and is also tapered longitudinally, as shown in Fig. 3 with its smaller end toward the cross bar 22.

Adapted to extend between each pair of lugs 24 is a removable connector pin 25 which is provided in its opposite ends with tapered dovetailed diametrical slots 26 which are adapted to receive and closely it the lugs 24 so that when the connector pin is in position between the two lugs, it cannot be drawn forwardly out of alinement with said lugs and will bind said lugs together so as to prevent an transverse spreading. of the free ends of tlie side bars 21. Each side bar 21 (and the cross-bar 22 in the forms shown in Figs. 1 and 2) is provided with an axial bore 27 adapted to receive and fit the connector pin 25` and to receive the lugs 24, the said lugs being properly shaped at their edges to enter the bores. At the end opposite lug 24, each side bar 21 is provided with a slot 28 which leads transversely into bore 27, each of said slot-s 28 having a proper dimension to permit the entrance of lugs 24. Thus far the two forms shown in Figs. 1 to 6 inclusive are identical but in the forms shown in Figs. 1, 3, 4, in order to form a further interlocking between adjacent links'I provided the side bar 21, with circular locking {iange 29 which is adapted to interlock behind a hook 31 carried by the opposite end of the adjacent side bars 21.v

The forms shown in Figs. 7 and 8 differ from the forms shown in Figs. 1 and 2 in that the side bars 21', instead of being integrally connected with the cross bar, are separate, and, instead of the cross bar 22 I provide a bearing roller 22 which serves as a separator for the bored ends of the side'bars and is rotatably mounted upon the connector pin 25 so as to thus provide a r'ollerinteraction with the sprocket wheel.

In assembling or separating the links they are brought to the osition shown in dotted lines in Fig. 3 and 1n full. lines at the right hand ends of Figs. l, 2, 7 and 8, so that the open ends of slots 28 are in position to receive the lugs`24, the connector pin 25 being first slipped into the bore 27 and its dovetailed slots 26 turned so that their wider ends will register with the inner ends of the slots 28 whereupon by a forward slidin and upward `turning movement of the lin as indicated b the arrows in Figs. 1 and 3, the parts may e assembled.
